BRUSH RIGGING.

Application filed June 9, 1923.

of New Jersey, have invented certain new and useful Improvements inBrush Rigging, of which the following is a specification.

The present invention relates to brush rigging and more particularly toa device for holding the brushes in toy electrical devices.

In manufacturing toy motors it is desirable to provide suitablebrushrigging which is capable oi easy disassembly for purposes ofrepairs, and for replacement of the brushes. In certain types of thesemotors, such as those designed for use in toy electric trains it isdesirable to arrange the brush rigging so that it can readily be removedcar or locomotive of which. it forms a part. The embodiments of theinvention to be described in the present application have been developedmore particularly for use with a toy electric locomotive or car.

Objects of the present invention areto provide a substantial brushrigging tor the above purposes which will be capable of easy removal forinspection and repairs, and 0 one which may be made in large quantitiesin an inexpensive manner so that all parts may be easilyinterchangeable.

Another object of the invention is to provide a brush rigging in whichthe brushes and supporting devices may be assembled as a unit and thenthis unit readily fastened in place alongside the comn'iutator withwhich the brushes are to cooperate.

In the accompanying drawings there. is shown for purposes ofillustration one of the many possible embodiments in which the presentinvention may take form, together with modifications of certain parts,it being understood that the drawings are to be conthan limiting thesame. In these drawings:

Fig. 8 illustrates a further modification.

Referring now to the Figs. 1 to 5 of the drawings, the side frame memberof the toy vehicle is shown at 10 in the form of a fiat piece of sheetmetal. This frame member carries the running gear here shown in the formof flanged wheels 11, 11 mounted on shafts, 12, 12. It is of courseunderstood that the other side of the vehicle is provided with asomewhat similar frame member. The frame member 10 is also provided witha hole 13 adapted to act as a bearing for the armature shaft 14 and withnotches 15 and 16 for purpose to be described. A flat sheet metal plate17 is provided with projections 18 and 19 which are adapted to tit intothe notches 15 and 16 in the frame member. The plate 1'7 is alsoprovided with a threaded aperture 20 to receive a screw 21 which ispassed through the frame member 10 from the outside as indicated in Fig.4 and, in dotted lines, in Fig. 1. The screw and the lugs and notchescooperate to removably fasten the plate in place on the side frame.

The plate 17 extends up above the armature shaft 14 as indicated in Fig.1, at 22 and 23. The metal between the upper p'ortions 22 and 23 of thisplate has been removed in order to provide an open slot which extendsall the way to the upper edge of the plate, the slot being made widerthan the commutator shown at 24.

A sheet of insulation 25 is fastened to the sheet metal plate 1'? bymeans of screws 26 and 27 and his sheet oi insulation, as is apparent inthe drawings, has two portions which extend upwardly past the armatureshaft. These upwardly extending portions are also separated in a mannersimilar to the parts and 23 of the plate 17. Sheet metal brush holders28 and 20 are fastened to the insulating sheet by means of screws 30and31, and prongs 32 passed through the insulation and bent over as shownin Fig. 3. These brush holders may be of any convenient form but arehere shownas made of a piece of sheet metal by suitably cutting andfolding the same. In addition to the prongs 32 above mentioned thesebrush holders are provided with brush boxes 33 adapted to containbrushes 3%, and with screw receiving apertures 35 adapted to receive thescrews 30 and 31. A prong 36 is located in a position to hold the brushspring when the brush is out of the box. The brush boxes'33 are cut awayas indicated at 33 so as to effectively clear the shoulder 2% on thearmature and permit the brush to cover practically the entire length ofthe comma: tator segment. The screws 30 and 31 in addition to fasteningthe brush holders to the insulation, each serve as a retainer for theupright portion 40 of the brush holder.

As shown in Figs. 1 and 2, armature leads I a1 and 42 may be connectedto the screws Hand 51 of sheet metal.

31 and 30. v

The plate 17 and insulating sheet 25'with brush holders attached make upan assembled unit which may be readily put into the machine. It is onlynecessary to slide this made up unit upwardly from the botv tom of thecar, bring the notches and pro.- jectionsin alignment and fasten theparts to the car by means of the screw'21. The leads are then connectedin place and the brushes inserted.

lVhen inspection is desired, or the boy usingthe car wants to satisfyhis natural curiosity, it is merely necessary to disconnect the armatureleads, take out thescrew 2 1 and slide the parts down away from thecommutator; The springs 37 may be placed on the prongs 36 to preventlosing the brushes by the springs throwing them away. It is, of course,obvious that the open slot inv the upper part of the sheet metal plateand the insulating sheet permit the withdrawal of the parts downwardly,In order to assist one in handling the parts there may be provided ifdesired a finger grip 43 which projects outwardly from the bottom of theframe member 10.

The structure shown in Figs. 6 and 7 is, in general, the same as that ofFigsal to 5, and corresponding reference characters are used forthecorresponding parts. Instead of leads in the form of wires fastened tothe brush holders, there are here shown leads or connectors in the formof bent pieces These connectors are preferably soldered to the brushholders at 59. and and are provided with out= wardlybent ends'54 and 55.The leads 56 for the armature circuit are passed through holes 57 in ablock of insulation 58 and are fastened to the bent ends 54 and byscrews 59 threaded into the insulation. The insu lating block is mountedon the locomotive in any convenient manner, and is cut away as shown at60 to provide space for inserting or removing the plate 17 and part-scarried thereby. As here shown, the block 58 also carries the currentcollecting devices 61 adapted to make contact with a third rail 62. Toremove this form of brush rigging the screws 59 and 21 are removed, andthe plate slid out of place.

The structure of Fig. 8 differs from that of Figs. 6 and 7 in that theblock of insulation 58 is provided with permanent binding posts 63 forthe'leads, andin that these binding posts have exposed contact surfaces6a to contact with the bent ends 65 and 66 of the leads or connectors 67and 68. This form of brush rigging may be removed bodily upon removal ofthe screw 2 1.
